SEESAW.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed March 26, 1920. Serial No. 389,059.

To all whom it may concern Be it known that I, Josnrrr F. DUNCAN, acitizen of the United States, residing at Etowah, in the county ofMcMinn and State of Tennessee, have invented new and useful Improvementsin Seesaws, of which the following is a specification.

This invention relates to a see-saw de vice and one of the objects ofthe invention is to provide means whereby the rocking member may beadjusted vertically on its support and also adjusted longitudinally onsaid support.

Another object of the invention is to pro vide a foot support on therocking member and also a support for engagement by the hands.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of the invention.

Fig. 2 is a plan View.

Fig. 3 is a sectional view through the suport. p Fig. 1 is a perspectiveview of one of the upright pieces which carries the handle and footbars.

F 5 is an end view of the rocking lever and its attached parts.

In these views 1 indicates the upright supporting member which consistsof the base 2 and the pair of uprights 3. The base con sists of a pairof pieces at crossing each other and each provided with a slot forreceiving a portion of the other piece. The lower ends of the uprightsare also provided with slots for receiving one of the cross piecesandthe uprights are bolted to the cross pieces by the bolts 5. It willbe seen that one of the cross pieces is located between the uprights sothat these uprights are spaced apart and the rocking member 6 is locatedin this space. The uprights are provided with a plurality of holes 7,any pair of which receiving the bolt 8 WlllCl'l supports the rockingmember. The lower edge of this member is provided with the spacedrecesses 9 for engaging the bolt. In this way the rocking member may beadjusted longitudinally to permit a person of light weight to occupy thedevice with a person of heavier weight. The rocking member can also beadjusted vertically by placing the bolt 8 in the dif ferent holes in theuprights.

A seat 10 is secured to the upper edge of the rocking member, at eachend thereof, and this seat is strengthened by an end piece 11 which issecured to each end of the rocking member and to the end edge of thebottom of the seat.

Upright pieces 12 are secured to the rocking member adjacent each seatand a handle bar 13 is passed through the upper ends of each pair ofthese pieces and a foot rest bar 14. is passed through their lower endsso as to provide a foot rest and a hand hold for the person occupyingeach seat. I prefor to extend the pieces carrying the foot and handrests a suflicient distance below the rocking member so that they willengage the ground and thus prevent the end of the said member fromstriking the ground. I may also place a reinforcing strap 15 of metal onthe upper edge of the rocking member.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

lVhat I claim is A see saw comprising an upright supporting frameconsisting of a pair of uprights and a pair of cross pieces connectedtogether, and to the uprights, one of said cross pieces spacing theuprights apart, a plurality of holes arranged in a vertical line in saiduprights, a bolt for engaging any pair of said holes, a rocking memberhaving a plurality of spaced recesses in its lower edge for receivingthe bolt, seats secured to the ends of the rocking member and a footrest and hand hold carried by the rocking member adjacent each seat.

In testimony whereof I aflix my signature.

JOSEPH F. DUNCAN.
